Extract the mail header in Mozilla Thunderbird

Quick reference guide to extract the mail header in Mozilla Thunderbird

To be able to trace an e-mail, the e-mail headers must be shown. Here you can follow the guide showing how to get mail header using Mozilla Thunderbird e-mail application.

If you receive some suspicious e-mail and want to report it to the e-mail group or to the security department, the unwanted e-mail must always be attached .

But there may be other situations where you should attach just the e-mail header, when it comes to troubleshooting, for example, for delayed e-mails.

Do like this:

  1. Start Thunderbird. Mark the suspicious e-mail and click on More. Click on View Source.
  2. Select and copy all text in the new window.
  3. Paste the text in the request you are about to send in.
